+%description
+Unbound is a validating, recursive, and caching DNS resolver.
+
+The C implementation of Unbound is developed and maintained by NLnet
+Labs. It is based on ideas and algorithms taken from a java prototype
+developed by Verisign labs, Nominet, Kirei and ep.net.
+
+Unbound is designed as a set of modular components, so that also
+DNSSEC (secure DNS) validation and stub-resolvers (that do not run
+as a server, but are linked into an application) are easily possible.
+
+The source code is under a BSD License.

+	- lowered log_hex blocksize to fit through BSD syslog linesize.
+	- no useless initialisation if getpwnam not available.
+	- iana, ldns snapshot updated.
+
+3 July 2008: Wouter
+	- Matthijs fixed memory leaks in root hints file reading.
+
+26 June 2008: Wouter
+	- fixup streamtcp bounds setting for udp mode, in the test framework.
+	- contrib item for updating trust anchors.
+
+25 June 2008: Wouter

+	  on windows.
+	- fwd_ancil test fails if platform support is lacking.
+
+23 June 2008: Wouter
+	- fixup minitpkg to cleanup on windows with its file locking troubles.
+	- minitpkg shows skipped tests in report.
+	- skip ipv6 tests on ipv4 only hosts (requires only ipv6 localhost not
+	  ipv6 connectivity).
+	- winsock event handler keeps track of sticky TCP events, that have
+	  not been fully handled yet. when interest in the event(s) resumes,
+	  they are sent again. When WOULDBLOCK is returned events are cleared.

+
+18 June 2008: Wouter

+17 June 2008: Wouter
+	- outgoing num fds 32 by default on windows ; it supports less
+	  fds for waiting on than unixes.

+	- neater crypto check and gdi32 detection.
+	- unbound.exe works to resolve and validate www.nlnetlabs.nl on vista.
+
+16 June 2008: Wouter
+	- on windows, use windows threads, mutex and thread-local-storage(Tls).
+	- detect if openssl needs gdi32.
+	- if no threading, THREADS_DISABLED is defined for use in the code.
+	- sets USE_WINSOCK if using ws2_32 on windows.
+	- wsa_strerror() function for more readable errors.
+	- WSA Startup and Cleanup called in unbound.exe.
+
+13 June 2008: Wouter
+	- port mingw32, more signal ifdefs, detect sleep, usleep, 
+	  random, srandom (used inside the tests).
+	- signed or unsigned FD_SET is cast.
+
+10 June 2008: Wouter
+	- fixup warnings compiling on eeepc xandros linux.
+
+9 June 2008: Wouter

+	    In response to error report by Richard Doty for mail.opusnet.com.
+	- fixup unput warning from lexer on freeBSD.
+	- bug#183. pidfile, rundir, and chroot configure options. Also the
+	  example.conf and manual pages get the configured defaults.
+	  You can use: (or accept the defaults to /usr/local/etc/unbound/)
+	  --with-conf-file=filename
+	  --with-pidfile=filename
+	  --with-run-dir=path
+	  --with-chroot-dir=path
+
+8 June 2008: Wouter
+	- if multiple CNAMEs, use the first one. Fixup akamai CNAME bug.
+	  Reported by Robert Edmonds.
+	- iana port updated.
+
+4 June 2008: Wouter
+	- updated libtool files with newer version.
+	- iana portlist updated.
+
+3 June 2008: Wouter
+	- fixup local-zone: "30.172.in-addr.arpa." nodefault, so that the
+	  trailing dot is not used during comparison.
+
+2 June 2008: Wouter
+	- Jelte fixed bugs in my absence
+	  - bug 178: fixed unportable shell usage in configure (relied on 
+	    bash shell).
+	  - bug 180: fixed buffer overflow in unbound-checkconf use of strncat.
+	  - bug 181: fixed buffer overflow in ldns (called by unbound to parse
+	    config file parts).
+	- fixes by Wouter
+	  - bug 177: fixed compilation failure on opensuse, the 
+	    --disable-static configure flag caused problems.  (Patch from 
+	    Klaus Singvogel)
+	  - bug 179: same fix as 177.
+	  - bug 185: --disable-shared not passed along to ldns included with 
+	    unbound. Fixed so that configure parameters are passed to the
+	    subdir configure script.
+	    fixed that ./libtool is used always, you can still override
+	    manually with ./configure libtool=mylibtool or set $libtool in
+	    the environment.
+	- update of the ldns tarball to current ldns svn version (fix 181).
+	- bug 184: -r option for unbound-host, read resolv.conf for 
+	  forwarder. (Note that forwarder must support DNSSEC for validation
+	  to succeed).
+
+23 May 2008: Wouter
+	- mingw32 porting.
+	  - test for sys/wait.h
+	  - WSAEWOULDBLOCK test after nonblocking TCP connect.

+	  - skip signals that are not defined
+	  - detect pwd.h.
+	  - detect getpwnam, getrlimit, setsid, sbrk, chroot.
+	  - default config has no chroot if chroot() unavailable.
+	  - if no kill() then no pidfile is read or written.
+	  - gmtime_r is replaced by nonthreadsafe alternative if unavail.
+	    used in rrsig time validation errors.
+
+22 May 2008: Wouter
+	- contrib unbound.spec from Patrick Vande Walle.

+7 May 2008: Wouter
+	- fixup no-ip4 problem with error callback in outside network.
+
+25 April 2008: Wouter

+	- contrib files unbound.spec and unbound.init, builds working RPM
+	  on FC7 Linux, a chrooted caching resolver, and libunbound.
+	- iana ports update.
+
+24 April 2008: Wouter
+	- chroot checks improved. working directory relative to chroot.

+	  and chroot was used.
+
+16 April 2008: Wouter
+	- requirements doc, updated clean query returns.
+	- parseunbound.pl update from Kai Storbeck.
+	- sunos4 porting changes.
+
+15 April 2008: Wouter
+	- fixup default rc.d pidfile location to /usr/local/etc.
+	- iana ports updated.
+	- copyright updated in ldns-testpkts to keep same as in ldns.
+	- fixup checkconf chroot tests a bit more, chdir must be inside
+	  chroot dir.
+	- documented 'gcc: unrecognized -KPIC option' errors on Solaris.
+	- example.conf values changed to /usr/local/etc/unbound
+	- DSA test work.
+	- DSA signatures: unbound is compatible with both encodings found.
+	  It will detect and convert when necessary.
+
+14 April 2008: Wouter
+	- got update for parseunbound.pl statistics script from Kai Storbeck.
+	- tpkg tests for udp wait list.
+	- documented 0x20 status.
+	- fixup chroot and checkconf, it is much smarter now.
+	- fixup DSA EVP signature decoding. Solution that Jelte found copied.
+	- and check first sig byte for the encoding type.
+
+11 April 2008: Wouter
+	- random port selection out of the configged ports.
+	- fixup threadsafety for libevent-1.4.3+ (event_base_get_method).
+	- removed base_port.
+	- created 256-port ephemeral space for the OS, 59802 available.
+	- fixup consistency of port_if out array during heavy use.
+
+10 April 2008: Wouter
+	- --with-libevent works with latest libevent 1.4.99-trunk.
+	- added log file statistics perl script to contrib.
+	- automatic iana ports update from makefile. 60058 available.
+
+9 April 2008: Wouter
+	- configure can detect libev(from its build directory) when passed
+	  --with-libevent=/home/wouter/libev-3.2
+	  libev-3.2 is a little faster than libevent-1.4.3-stable (about 5%).
+	- unused commpoints not listed in epoll list.
+	- statistics-cumulative option so that the values are not reset.
+	- config creates array of available ports, 61841 available,
+	  it excludes <1024 and iana assigned numbers.
+	  config statements to modify the available port numbers.
+
+8 April 2008: Wouter
+	- unbound tries to set the ulimit fds when started as server.
+	  if that does not work, it will scale back its requirements.
+
+27 March 2008: Wouter
+	- documented /dev/random symlink from chrootdir as FAQ entry.
+
+26 March 2008: Wouter
+	- implemented AD bit signaling. If a query sets AD bit (but not DO)
+	  then the AD bit is set in the reply if the answer validated.
+	  Without including DNSSEC signatures. Useful if you have a trusted
+	  path from the client to the resolver. Follows dnssec-updates draft.
+
+25 March 2008: Wouter
+	- implemented check that for NXDOMAIN and NOERROR answers a query
+	  section must be present in the reply (by the scrubber). And it must
+	  be equal to the question sent, at least lowercase folded.
+	  Previously this feature happened because the cache code refused
+	  to store such messages. However blocking by the scrubber makes 
+	  sure nothing gets into the RRset cache. Also, this looks like a
+	  timeout (instead of an allocation failure) and this retries are
+	  done (which is useful in a spoofing situation).
+	- RTT banding. Band size 400 msec, this makes band around zero (fast)
+	  include unknown servers. This makes unbound explore unknown servers.
+
+7 March 2008: Wouter
+	- -C config feature for harvest program. 
+	- harvest handles CNAMEs too.
+
+5 March 2008: Wouter
+	- patch from Hugo Koji Kobayashi for iterator logs spelling.
+
+4 March 2008: Wouter
+	- From report by Jinmei Tatuya, rfc2181 trust value for remainder
+	  of a cname trust chain is lower; not full answer_AA. 
+	- test for this fix.
+	- default config file location is /usr/local/etc/unbound.
+	  Thus prefix is used to determine the location. This is also the
+	  chroot and pidfile default location.
+
+3 March 2008: Wouter
+	- Create 0.10 svn tag.
+	- 0.11 version in trunk.
+	- indentation nicer.
+
+29 February 2008: Wouter
+	- documentation update.
+	- fixup port to Solaris of perf test tool.
+	- updated ldns-tarball with decl-after-statement fixes.
+
+28 February 2008: Wouter
+	- fixed memory leaks in libunbound (during cancellation and wait).
+	- libunbound returns the answer packet in full.
+	- snprintf compat update.
+	- harvest performs lookup.
+	- ldns-tarball update with fix for ldns_dname_label.
+	- installs to sbin by default.
+	- install all manual pages (unbound-host and libunbound too).
+
+27 February 2008: Wouter
+	- option to use caps for id randomness.
+	- config file option use-caps-for-id: yes
+	- harvest debug tool
+
+26 February 2008: Wouter
+	- delay utility delays TCP as well. If the server that is forwarded 
+	  to has a TCP error, the delay utility closes the connection.
+	- delay does REUSE_ADDR, and can handle a server that closes its end.
+	- answers use casing from query.
+
+25 February 2008: Wouter
+	- delay utility works. Gets decent thoughput too (>20000).
+
+22 February 2008: Wouter
+	- +2% for recursions, if identical queries (except for destination
+	  and query ID) in the reply list, avoid re-encoding the answer.
+	- removed TODO items for optimizations that do not show up in
+	  profile reports.
+	- default is now minievent - not libevent. As its faster and
+	  not needed for regular installs, only for very large port ranges.
+	- loop check different speedup pkt-dname-reading, 1% faster for
+	  nocache-recursion check.
+	- less hashing during msg parse, 4% for recursion.
+	- small speed fix for dname_count_size_labels, +1 or +2% recursion.
+	- some speed results noted:
+	  optimization resulted in +40% for recursion (cache miss) and
+	  +70 to +80 for cache hits, and +96% for version.bind.
+	  zone nsec3 example, 100 NXDOMAIN queries, NSD 35182.8 Ub 36048.4
+	  www.nlnetlabs.nl from cache: BIND 8987.99 Ub 31218.3
+	  www with DO bit set : BIND 8269.31 Ub 28735.6 qps.
+	  So, unbound can be about equal qps to NSD in cache hits.
+	  And about 3.4x faster than BIND in cache performance.
+	- delay utility for testing.
+
+21 February 2008: Wouter
+	- speedup of root-delegation message encoding by 15%.
+	- minor speedup of compress tree_lookup, maybe 1%.
+	- speedup of dname_lab_cmp and memlowercmp - the top functions in 
+	  profiler output, maybe a couple percent when it matters.
+
+20 February 2008: Wouter
+	- setup speec_cache for need-ldns-testns in dotests.
+	- check number of queued replies on incoming queries to avoid overload
+	  on that account.
+	- fptr whitelist checks are not disabled in optimize mode.
+	- do-daemonize config file option.
+	- minievent time share initializes time at start.
+	- updated testdata for nsec3 new algorithm numbers (6, 7).
+	- small performance test of packet encoding (root delegation).
+
+19 February 2008: Wouter
+	- applied patch to unbound-host man page from Jan-Piet Mens.
+	- fix donotquery-localhost: yes default (it erroneously was switched
+	  to default 'no').
+	- time is only gotten once and the value is shared across unbound.
+	- unittest cleans up crypto, so that it has no memory leaks.
+	- mini_event shares the time value with unbound this results in 
+	  +3% speed for cache responses and +9% for recursions.
+	- ldns tarball update with new NSEC3 sign code numbers.
+	- perform several reads per UDP operation. This improves performance
+	  in DoS conditions, and costs very little in normal conditions.
+	  improves cache response +50%, and recursions +10%.
+	- modified asynclook test. because the callback from async is not
+	  in any sort of lock (and thus can use all library functions freely),
+	  this causes a tiny race condition window when the last lock is 
+	  released for a callback and a new cancel() for that callback.
+	  The only way to remove this is by putting callbacks into some 
+	  lock window. I'd rather have the small possibility of a callback
+	  for a cancelled function then no use of library functions in 
+	  callbacks. Could be possible to only outlaw process(), wait(),
+	  cancel() from callbacks, by adding another lock, but I'd rather not.
+
+18 February 2008: Wouter
+	- patch to unbound-host from Jan-Piet Mens.
+	- unbound host prints errors if fails to configure context.
+	- fixup perf to resend faster, so that long waiting requests do
+	  not hold up the queue, they become lost packets or SERVFAILs,
+	  or can be sent a little while later (i.e. processing time may 
+	  take long, but throughput has to be high).
+	- fixup iterator operating in no cache conditions (RD flag unset
+	  after a CNAME).
+	- streamlined code for RD flag setting.
+	- profiled code and changed dname compares to be faster. 
+	  The speedup is about +3% to +8% (depending on the test).
+	- minievent tests for eintr and eagain.
+
+15 February 2008: Wouter
+	- added FreeBSD rc.d script to contrib.
+	- --prefix option for configure also changes directory: pidfile:
+	  and chroot: defaults in config file.
+	- added cache speed test, for cache size OK and cache too small.
+
+14 February 2008: Wouter
+	- start without a config file (will complain, but start with
+	  defaults).
+	- perf test program works.
+
+13 February 2008: Wouter
+	- 0.9 released.
+	- 1.0 development. Printout ldns version on unbound -h.
+	- start of perf tool.
+	- bugfix to read empty lines from /etc/hosts.
+
+12 February 2008: Wouter
+	- fixup problem with configure calling itself if ldns-src tarball
+	  is not present.
+
+11 February 2008: Wouter
+	- changed library to use ub_ instead of ub_val_ as prefix.
+	- statistics output text nice.
+	- etc/hosts handling.
+	- library function to put logging to a stream.
+	- set any option interface.
+
 8 February 2008: Wouter
 	- test program for multiple queries over a TCP channel.
 	- tpkg test for stream tcp queries.
 	- unbound replies to multiple TCP queries on a TCP channel.
+	- fixup misclassification of root referral with NS in answer
+	  when validating a nonrec query.
+	- tag 0.9
+	- layout of manpages, spelling fix in header, manpages process by
+	  makedist, list asynclook and tcpstream tests as ldns-testns
+	  required.
 
 7 February 2008: Wouter
 	- moved up all current level 2 to be level 3. And 3 to 4.

+Unbound Features
+
+(C) Copyright 2008, Wouter Wijngaards, NLnet Labs.
+
+
+This document describes the features and RFCs that unbound 
+adheres to, and which ones are decided to be out of scope.
+
+
+Big Features
+------------
+Recursive service.
+Caching service.
+Forwarding and stub zones.
+No authoritative service.
+DNSSEC Validation options.
+EDNS0, NSEC3, Unknown-RR-types.
+
+
+Details
+-------
+Processing support
+RFC 1034-1035: as a recursive, caching server. Not authoritative.
+  including CNAMEs, referrals, wildcards, classes, ...
+RFC 4033-4035: as a validating caching server (unbound daemon). 
+  as a validating stub (libunbound).
+RFC 1918.
+RFC 2181: completely, including the trust model, keeping rrsets together.
+RFC 2672: DNAME support.
+RFC 3597: Unknown RR type support.
+RFC 2671: EDNS0 support, default advertisement 4Kb size. 
+RFC 5155: NSEC3, NSEC3PARAM types
+AAAA type. and IP6 dual stack support.
+type ANY queries are supported.
+RFC 2308: TTL directive, and the rest of the RFC too.
+RFC 4592: wildcards.
+
+RFC 1995, 1996, 2136: not authoritative, so no AXFR, IXFR, NOTIFY or
+  dynamic update services are appropriate.
+
+chroot and drop-root-privileges support, default enabled in config file.
+
+AD bit in query can be used to request AD bit in response (w/o using DO bit).
+CD bit in query can be used to request bogus data.
+UDP and TCP service is provided downstream.
+UDP and TCP are used to request from upstream servers.
+Multiple queries can be made over a TCP stream.
+
+No TSIG support at this time.
+No SIG0 support at this time.
+No dTLS support at this time.
+This is not a DNS statistics package, but some operationally useful
+values are provided.
+TXT RRs from the Chaos class (id.server, hostname.bind, ...) supported.
+
+draft-forgery-resilience: all recommendations followed.
+draft-0x20: experimental implementation (incomplete).
+  implements bitwise echo of the query to support downstream 0x20.
+draft-ietf-dnsop-default-local-zones is fully supported (-04).
+  It is possible to block zones or return an address for localhost.
+  This is a very limited authoritative service. Defaults as in draft.
+draft-ietf-dnsop-resolver-priming(-00): can prime and can fallback to 
+  a safety belt list.
+draft-ietf-dnsop-dnssec-trust-anchor(-01): DS records can be configured 
+  as trust anchors. Also DNSKEYs are allowed, by the way.
+draft-ietf-dnsop-reflectors-are-evil: access control list for recursive
+  service. In fact for all DNS service so cache snooping is halted.
+
+Record type syntax support, extensive, from lib ldns.
+For these types only syntax and parsing support is needed.
+RFC 1034-1035: basic RR types.
+RFC 1183: RP, AFSDB, X25, ISDN, RT
+RFC 1706: NSAP
+RFC 2535: KEY, SIG, NXT: treated as unknown data, syntax is parsed (obsolete).
+2163: PX
+AAAA type
+1876: LOC type
+2782: SRV type
+2915: NAPTR type.
+2230: KX type.
+2538: CERT type.
+2672: DNAME type.
+OPT type
+3123: APL
+SSHFP type
+4025: IPSECKEY
+4033-4035: DS, RRSIG, NSEC, DNSKEY
+4701: DHCID
+5155: NSEC3, NSEC3PARAM
+4408: SPF

+ *
+ * At each label:
+ *	SOA
+ *	NS
+ *	DNSKEY
+ *	DS
+ * For the whole query:

+ * Any NSEC, NSEC3, SOA records or additional data found in answers.
+ *
+ * All of this is data that would be encountered during an iterative lookup
+ * for the queries in the list. It is saved to enable a replay of iterative
+ * lookups for performance testing.
+ *
+ * A number of assumptions are made.
+ * 1) configuration is correct.
+ *    The parent has the same NS records as the child.
+ *    All nameservers carry the same data.
+ * 2) EDNS/nonEDNS responses and other behaviour is ignored.
+ *    Only the data is saved.
